as far as I've gotten
made a new rounding function. didn't help
possibly fixed "randomly going outside search extents" due to rounding
killed statements that created logs
fixed sorting and other changes

removed defunct function
removed some duplicate conversion
removed legacy code that was useless
did some cleaning. removed object "conversions"

it only contained data duplicated in the "obs" object after the change
from gridding to recursion
fixed issue #32 and cleaned up some code
further code cleanup
